Heather has a bag of 15 red, 11 orange, 9 yellow, 12 green, 6 blue and 11 purple markers. how many times would you expect heather to pick a red marker if she picked a marker 90 times? A. about 11 times
B. about 15 times
C. about 21 times
D. about 64 times

B should be the correct answer.

Step-by-step explanation:

15 + 11 + 9 + 12 + 6 + 11 = 64

64<90

15 red out of 64 total markers

15 / 64 = .234375

90 x .234375 = 21.09375

so she will pick a red marker about 21 times

Step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
